Faculty & Staff

VSA faculty are leaders in their fields and experts in the topics they teach. They all meet Victoria’s highest standards for teaching her program and share the same positive philosophy. During two in-person Intensives, faculty will teach you via multimedia presentations, group discussions, hands-on teaching and training activities, and real-time observation exercises and field trips. During bi-weekly Cyber-classes faculty will enrich important course topics while keeping you engaged with other students and on track with your course work. Our small class sizes ensure that you’ll work closely with VSA faculty.

Throughout your program of study, VSA Faculty will immerse you in topics and observation from their “lens” of experience, deepening and enhancing your understanding of the material in a way that simply doesn’t happen through a distance learning course.
